How to Remove Nicotine Stains From Lips

Author
by 

Cigarette smoking takes a toll on the body, accelerating the aging process by causing early wrinkles and discoloring the teeth, hair and skin. Nicotine also breaks down collagen and causes unsightly brown stains on the lips, resulting in a kisser that is anything but kissable. Quitting smoking is the only way to return nicotine-stained lips to their normal appearance. However, you can minimize the brown stains and improve the appearance of your lips until you are ready to break the habit for good.

Step 1

Exfoliate your lips with a mild scrub once every week. Although you can use a commercial scrub, you can make a scrub at home by mixing brown or white sugar, almond oil and honey.

Step 2

Apply a lip balm or lipstick containing sunscreen every time you go outdoors. Look for products with an SPF factor of at least 15. Use fresh, high-quality lipstick, and discard old, outdated products.

Step 3

Smooth a moisturizer such as petroleum jelly, vitamin E oil or lip balm on your lips every night.

Step 4

Make a paste of lemon or lime juice, honey, and plain, full-fat yogurt. Smooth the paste on your lips and leave it for 30 minutes, then rinse. Apply as needed to soften and lighten the lips.

Step 5

Drink at least eight glasses of water daily to keep your lips hydrated.

How to Remove Smoking Wrinkles

Author
by 

Cigarette smoking causes premature aging and symptoms such as wrinkles and lines. According to the Mayo Clinic, nicotine in cigarettes narrow blood vessels in the outer layers of skin and reduce blood flow to these areas. As a result, your skin is deprived of the oxygen and nutrients it needs to stay healthy and youthful. While fine lines above the lips and elsewhere on your face are the most visible, smoking also causes wrinkles elsewhere such as your inner arms, states the Mayo Clinic. Removing or reducing wrinkles can be challenging, but you have a few options at your disposal.

Step 1

Stop smoking. It’s counterproductive to attempt to treat wrinkles if you continue the habit that’s causing them. As the Mayo Clinic points out, cigarettes also contain other toxic chemicals that break down collagen and elastin and cause wrinkles. Plus, being exposed to heat from cigarettes and making repeated facial expressions while smoking also increase wrinkles and lines. Get advice from your doctor about quitting cold turkey or nicotine replacement therapies.

Step 2

Wash your face and body with mild, moisturizing soaps or liquid cleansers to limit dryness, which makes skin more likely to wrinkle.

Step 3

Moisturize your skin while it’s still damp with a coenzyme Q10 cream or gel. According to Hirsh Dermatology in Ohio, this antioxidant protects skin from substances that break down collagen. Or, apply a vitamin E cream, which reduces the depths of wrinkles. Also, alpha hydroxy acid skin products boost collagen and elastin content in the skin to reduce wrinkles.

Step 4

Eat foods rich in vitamin C such as oranges, grapefruits, papayas and red bell peppers, or take a daily vitamin C supplement. This nutrient is a key building block of collagen and is also a potent antioxidant that helps protect the skin from wrinkling.

Step 5

Apply a broad spectrum sunscreen at least 20 minutes before you go outdoors. Sun exposure is the leading cause of wrinkles, according to the American Academy of Dermatology. It damages collagen and impairs collagen synthesis, making any damage your skin has suffered from smoking even worse.

Highlights

A facile sonication route to produce aqueous wax dispersions is developed.
The wax dispersion is naturally stable and free of surfactants or stabilizers.
Wax and ZnO particles are coated onto wood using layer-by-layer assembly.
The coating brings superhydrophobicity while preserving moisture buffering.
ZnO improves the color stability of wood to UV light.

Abstract

Protection from liquid water and UV radiation are equally important, and a sophisticated approach is needed when developing surface coatings that preserve the natural and well-appreciated aesthetic appearance of wood. In order to prevent degradation and prolong the service life of timber, a protective coating was assembled using carnauba wax particles and zinc oxide nanoparticles via layer-by-layer deposition in water. For this purpose, a facile sonication route was developed to produce aqueous wax dispersion without any surfactants or stabilizers. The suspension was stable above pH 4 due to the electrostatic repulsion between the negatively charged wax particles. The particle size could be controlled by the initial wax concentration with average particle sizes ranging from 260 to 360 nm for 1 and 10 g/L, respectively. The deposition of wax particles onto the surface of spruce wood introduced additional roughness to the wood surface at micron level, while zinc oxide provided nano roughness and UV-absorbing properties. In addition to making wood superhydrophobic, this novel multilayer coating enhanced the natural moisture buffering capability of spruce. Moreover, wood surfaces prepared in this fashion showed a significant reduction in color change after exposure to UV light. A degradation of the wax through photocatalytic activity of the ZnO particles was measured by FTIR, indicating that further studies are required to achieve long-term stability. Nevertheless, the developed coating showed a unique combination of superhydrophobicity and excellent moisture buffering ability and some UV protection, all achieved using an environmentally friendly coating process, which is beneficial to retain the natural appearance of wood and improve indoor air quality and comfort.

Highlights

ZnO nanorod arrays were deposited on the wood surface via a hydrothermal process.
The assembled ZnO nanorod arrays greatly enhanced the photostability of wood.
The treated wood can sustain direct exposure to flame with only minor smoldering.
The ZnO-coated wood modified with stearic acid showed a superhydrophobic surface.

Abstract

Zinc oxide (ZnO) nanorod arrays were successfully assembled on the wood surface in situ via a two-step process consisting of formation of ZnO seeds and subsequent crystal growth under hydrothermal conditions at a low temperature. The morphology and crystalline structure of the formed ZnO nanorods were studied by field-emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). Highly dense and uniform arrays of ZnO nanorods with well-defined hexagonal facets were generated on the wood surface by tuning the concentration of the ZnO growth solution during the hydrothermal treatment. Accelerated weathering tests indicated that the assembled ZnO nanorod arrays were highly protective against UV radiation and greatly enhanced the photostability of the coated wood. Meanwhile, the ZnO nanorod-coated wood can withstand continuous exposure to flame with only minor smoldering in contrast with the pristine wood catching fire easily and burning rapidly. Moreover, when further modified with low-surface-energy stearic acid, the ZnO nanorod decorated wood surface can be transformed into a superhydrophobic surface, with a water contact angle (CA) of ∼154°. Such ZnO nanorod-modified woods with enhanced photostability, flame retardancy and water repellency offer an interesting alternative to conventional wood preservation strategies, highlighting their potential applications in some novel wood products.

Moisture absorption properties of hardwood veneers modified by a sol-gel process

Author
Edgars Kirilovs / Silvija Kukle / Janis Gravitis / Hans-Jörg Gusovius
Published Online: 2017-04-20 | DOI: https://doi.org/10.1515/hf-2016-0151

Abstract

A new invisible nanolevel coating has been developed based on the sol-gel process for veneer finishes. The sol synthesis and its application as a protective agent is described. It could be demonstrated that a combination of organic light stabilizers and sol-gel deposits is feasible and that the resulting hybrid inorganic-organic thin films decrease moisture uptake of hardwood veneers.
